Description
Technical field
The present invention relates to a kind of communications field, particularly to method, terminal unit and the base station of a kind of delay dispatching request (SR, Scheduling Request).
Background technology
The access network ubiquitous in order to realize user, terminal unit needs to install many set transceivers to access different networks.Such as, terminal unit can be simultaneously installed with Long Term Evolution (LTE, Long Term Evolution) system, the transceiver of industrial scientific medical (ISM, Industrial Scientific Medical) system (such as WiFi, bluetooth BlueTooth etc.).Owing to set transceiver distances many in same terminal unit are very near, the power of a system transmitter may be far above the power of another one system receiver.
Fig. 1 gives the example of an interference co-existence, as it is shown in figure 1, terminal unit can include LTE system, GPS system and bluetooth/WiFi system, LTE system may produce interference to bluetooth/WiFi system, and bluetooth/WiFi system is likely to LTE system is produced interference.If the working band of different system is spaced farther out, can well control to launch the signal docking collection of letters number interference caused by filtering technique.
But, for some scene, such as, when in same terminal unit the working frequency range of different system closely time, current filtering technique is not enough to provide effective interference to avoid.Therefore for such scene, in order to the interference realized when multiple systems transceiver in terminal unit coexists is avoided, in addition to filtering technique, in addition it is also necessary to the method considering other.
At present, 3GPP mainly considers the scene of following coexistence of systems.
(1) LTE and WiFi system coexist
(2) LTE and Bluetooth coexistence of systems
(3) LTE and GLONASS (GNSS, Global Navigation Satellite System) coexist
And in the scene that said system coexists, it may appear that interference problem include:
(1) at the Band 40 of LTE system, the signal of ISM system can be received and interfere by the signal transmission of LTE system；
(2) at the Band 40 of LTE system, the signal of LTE system can be received and interfere by the signal transmission of ISM system；
(3) at the Band 7 of LTE system, the signal of ISM system can be received and interfere by the signal transmission of LTE system；
(4) at the Band 7/13/14 of LTE system, the signal of GNSS system can be received and interfere by the signal transmission of LTE system
In order to avoid the mutual interference under above-mentioned scene, one of which method is to use time-multiplexed mode, is sent by the signal of two different systems and signal receives and separates from the time.Fig. 2 is that terminal unit at different reception LTE system signals and sends WiFi or the example schematic of Bluetooth signal.
At present, 3GPP defines two kinds and realizes time-multiplexed method.Including:
(1) based on the method that HARQ (HARQ) process is reserved.The time relationship of the HARQ process that the method defines according to LTE system, for LTE system reserved part subframe, and distributes to ISM system by remaining subframe, and i.e. in remaining subframe, device end can carry out transmission and the reception of ISM system data.
(2) method of discontinuous reception (DRX) based on LTE system.The method utilizes the DRX mechanism of current LTE system, and after the LTE transceiver of terminal unit enters resting state, terminal unit can carry out transmission and the reception of ISM system data.
In order to realize the method, terminal unit need to send to base station its desired LTE system and the cycle of ISM system work and within this cycle working time of LTE system and the working time (hereafter known as TDM pattern) of ISM system, and other some auxiliary information, such as, interference type, coexistance model etc..Then finally determined the TDM pattern of LTE system and ISM coexistence of systems by base station, and realize this TDM pattern by the parameter of suitable configuration DRX.Fig. 3 illustrates the TDM pattern that a terminal unit is advised to base station.Fig. 4 illustrates a TDM pattern according to this suggestion, the configuration of the DRX that base station finally determines.
But, during realizing the present invention, inventor finds that the defect of prior art is: in the case of LTE and ISM coexists, when using DRX mechanism, if terminal unit has come into ISM duty, after the upstream data having LTE system arrives, if triggering dispatch request or Stochastic accessing immediately according to the method for current LTE, ISM system and LTE system so can be caused simultaneously to work, therefore can cause interference from each other.
It should be noted that introduction to technical background above is intended merely to convenient technical scheme carry out clear, complete explanation, and facilitate the understanding of those skilled in the art to illustrate.Can not be merely because these schemes be set forth at the background section of the present invention and think that technique scheme is known to those skilled in the art.
